SPECIFICATION forming part of Letters Patent No. 519,948, dated May 15, 1894.

Application tiled May 27, 1893. SerialNo. 475,759. (Model.)

To @ZZ whom t may concern:

Be it known lthat I, ARTHUR W. HAHN, of New York city, in the county and State of New York, have invented a new and Improved Brush for Nursing-Bottles, ot which the following is a full, clear, and exact description.

My invention relates to an improvement in brushes, especially brushes adapted for use 1n cleaning nursing bottles, or like vessels or receptacles; and the object of the invention is to provide a brush in which the bristle or cleaning section thereof will be removably connected with the back section, thereby admitting of a brush Section being removed from the back when unfit for use and another brush section substituted.

A further object of the invention is to so construct the brush section that any one capable of using the brush may apply a. brush section to a back section.

Another feature of the invention consists in not attaching the bristles directly to the back section, but in bunching and securing bristles in brush form independent of the back, and in so attaching the brush section to the back section that a cleaning surface will be obtained practically on three sides of the back and at one end thereof.

Theinventionconsistsin the novel construction and arrangement of the several parts, as will be hereinafter fully set forth, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the brush, illustrating its application toa bottle. Fig. 2 is a partial side elevation and partialsectional View of the back section, and a longitudinal section through the brush section, illustrating the manner in which it is applied to a back section. Fig. 8 is a plan view of a slightly modified brush; and Fig. l is a partial plan view of the back with the brush section detached.

The back section A of the brush is provided usually at one end with a crank arm 10, which crank arm serves as a handle; and the handle member of the crank arm may be given any shape that fancy may dictate or convenience may demand. The back, from the crank arm to a point near its center, is preferably made substantially straight, as illustrated at ll in the drawings; and where the straight portion of the back ends the said back is curved or depressed in adownward direction, and is then straight throughout the rest of its length. Ordinarily the depressed portion of the back is flattened, as at this point the bristle or cleaning section B of the brush is to be attached; but the other portions of the back may be made, and preferably are made circular in cross section, and usually the entire back is made from a single piece of wire rod.

The brush or bristle section B of the brush Y may be made of any desired length, and the bristles or any substitute therefor thatmay be employed, are secured in any suitable or approved manner to a core 12, preferably of a fieXible character. In fact, the core is ordinarily made of twisted wire of suitable size, and the bristles or other substitute that may be employed, are held in engagement with the core, the attachment being so eected that the bristles radiate from the core in direction of all sides, or practically so. The flattened or outer depressed portion of the back is ordinarily provided near its inner end with an aperture 13, and at its outer extremity the said depressed portion of the back is provided with arecess 14C and an aperture l5 adjacent to the recess, as shown in Fig. 4.

The cleaning or bristle section of the brush is attached to the back in the following manner: One end of the wire core 12 of the cleaning or bristle section is passed down through the aperture 15, and then the said section is carried around the end of the back section, the wire or core entering the recess 14. thereof, and thence along the under surface of the said back section to the aperture 13, when the other end of the core l2 is passed up through said aperture and bent down upon the back section as shown most clearly in Fig. 2. When the core is ca rried up over'the end of the brush, the bristles are carried up with it, so that the outer end of the back is con cealed or covered by bristles; and it will be readily observed that practically the cleaning or bristle section is attached to the back section at two points only, and that while it ICO vvill remain firmly in place it may be expeditiously and conveniently removed from the back when Worn or unt for use, and another bristle section may be `substituted for it by any one having the power to bend the core. In Fig. 3 I have shown a slight modification in which one end of the core is tied around the back instead of being passed through the l further desire it to aperture in the back. be understood that although the shape of back illustrated in the drawings is preferred, it may have other cross sectional shape, or it maybe made straight if in practice itis found desirable; but by depressing the brush end of the back, and forming a crank arm at the handle end, the brush may bc'turned in a bottle or decanter, for example, as shown in Fig. l, in such manner that the bristle or cleaning section Will engage with the entire interior surface of the bottle when the handle section is revolved, and the bristles at the end of the gaz/: will thoroughly clean the bottom ofthe Such a brush is exceedingly simple, it is durable and it is economic in its construction, and it is especially adapted for cleaning a nursing bottle, as all the crevices may be reached with it, and none of the inner surface will escape from the action of thebrush.

Having thus described my invention, I claim as new and desire to secure by Letters Patentv A brush comprising a back section having a recess in one end, and an aperture adjacent to said recess, and a brush section provided with a Wire core having projecting ends said brush section having one end of its core secured in the aperture ofthe back section with the cere resting in the recess of said back section, and the other end of its core secured .to the back section, substantially as herein shown and described.
